Abstract: A phacoemulsification irrigation sleeve 10 is formed of compliant material. The sleeve 10 is for surrounding at least a portion of a phacoemulsification needle 12 and for transporting irrigation fluid between the needle 12 and the sleeve 10. The sleeve 10 includes at least one irrigation port 16 formed in a shaft 18 of the sleeve 10 near a distal end 20 of the shaft 18. An alignment mark 22 of contrasting color relative to a color of the sleeve 10 is placed on the sleeve 10 in a predetermined orientation with respect to the irrigation port 16.

Abstract: A stent is made from a coiled wire and is very smooth along its length and as well its ends. The stent is thus highly atraumatic to patients, and because of its smooth surfaces, it presents a surface to which it is difficult for microbes to cling. The stent may be used in a minimally invasive procedure, such as for a ureteral stent, and may also be used percutaneously. Similar stents may be used in other body areas, such as in draining the biliary tract, the gastro-intestinal tract, hepatic procedures, and in vascular procedures as well.
